But there was disappointment for Tesco, whose Expert Lemon picked up the (dirty) wooden spoon for finishing last.

Nearly 15,000 plates

Aldi's Magnum Premium Original scored 89% in the consumer watchdog's test, washing 14,873 plates per £1. Almost three times per £1 compared to Fairy Platinum (5,069). In contrast, Tesco's offering scored just 37%.

"Washing-up may not be everyone's favourite thing to do," says Aldi buying boss Tony Baines, "but our brand new washing-up liquid shows that you don't have to spend a fortune to make this mundane household chore a little bit easier."

Aldi's market share is now approaching that of Waitrose's (Waitrose recently warned on profits). However while some people might cheer Aldi and Lidl on as the perceived, plucky underdog, in reality they're enormous (in Germany they take around 25% of the total market).

The current UK supermarket war has claimed the two top jobs at Tesco's. Ex chief exec Philip Clarke has been replaced by Dave Lewis and finance head Laurie Mcllwee has been replaced by Alan Stewart.

Tesco shares, currently at 246p, are down around 26% from the start of the year. Morrisons shares are down almost 33% since the beginning of the year, at 176p.
